12' Claims.

This invention relates to devices for preventing fire, smoke, airdrafts,vermin *and water drippings from running along 'ithe exterior of ipipelines.

In present building and-similar structures there usually exist cracks,fissures, openings for weaknesses around drain, water, heating,'etc.,jpipes.

Such cracks or openings formpassa'ges as Well a hidi g places forvermin. Furthermore, in

case offa fire starting on one floor of a building, such cracks,openings, etc.,wi ll.be inducive to drafts carrying smoke, sparks andfiames'irom one floor to another, thereby spreading thefire "hazard.

As a result ofwashing of fioorsor accidental flooding of floors, water'may fiow-along the pipes through the cracks or openings 'irom the-fioorabove to the floor below. Furthermore, pipes carryin water or wastematter are inclined to sweat or drip causing thematerial'theresurrounding to become moist, damp and/or discolored.

It is an object of the, present invention t-o'provide a'seal for anopening ina'structurethrough which a pipe lineor the like passes,theise'alin eluding a pipe fitting connecting with the pipe lineand'forming a-continuation thereof.

It isa further object of the present invention to provide such a sealwith drainage means to drain off any liquids whichmaylhave accumulatedthereon by reason of the sweating of the pipe or otherwise. v

It is a still further object of the present, invention to providea sealaround'heating, water and other pipes passing from one fl-oor toanother'of a structure, which will enhance the appearance of thatportion :of the door or ceiling through which such pipes pass, aswe-llasp vent passage of foreign matter, including vermin and Water, throughthe floors and'ceilingsof the structure.

It is yet another object of the present invention to create an adequatefire'stop adapted with pipe connections, to which necessary'pipe linesin the buildings are attached, thus avoiding openings within theconstruction of theibuildings ad- 'ja'cent pipelines which would-createdraits fanningx-a blaze in the event of 'fire breakingiout at any onepoint near the said device.

With the above and other'e'nds in view, "and in attaining the above andother objects and ad vantages, to be hereinafter set 'forth,the-invention consists in the .rnatters hereinafter setout,

and more particularly pointed out in the appended claims, referencebeing made to the accompanying drawings, in which:

.Referr'ingnow more particularly to thedr'awings, there is disclosed inFig. 1 :apipingwdiagram generally designated by the letter A passingthrough successive floor beams 15,16 and-l1 of successive tiers of'beams of "a building (not shown). These floor beams 15, i5 and 'H areprovided with'pipepassagesor openings 48, I9 and 2 0, respectively.These passage on openings are closed by means of pan members or plates2!, 22 and "23, respectively, "also generally indicated by the letter Pand substantiallythefdepth of the floonbeams. These plates'arepreferablymade of suitable metaland are provided with pip members or pipefittings, such as valves 24, connecting pipes 25, pipe'nipples 26,branchfittings 21, connecting Ts-21a,'etc. These members or fittings aremade integral withipan or plate-like member 24'during themanufacturethereof, the same being provided by forming suitable openings ofpredetermined sizes during casting ofthe requirements of 'a paiticu larbuildingin which they are tobe used. Fig. lit-shows the'p'late LPhaving:formed :tii'ereina trap T having theiconventional plug T"and alsoportions of pip 38 "connectedin a com/em tional manne'r'to plate P. This.tnap when formed in the plateeliminates"additional n oints and preventsleaks.

and-nipples 62. a 1 "Some of the pipe fittings .be conventional wastepipe fittings 63 having two inlets 64, 65, connected by means of ahorizontal branch 66, thus forming a Y fitting. Many Fig. 3 is anenclosure 48 to conceal the piping arrangement of the building providedin a shaft having a rear partition W. This shaft may contain ahorizontal partition H and a vertical partition V dividing the saidenclosure 48 into the compartments A, B, C and D between the floor F andceiling C. The space in these compart* ments through which respectivepipes pass, may

i said compartments to drain the same into a drain pipe 35. Also it ispreferable to providea sprinkler or' extinguisher 4001 43 in eachcompartment to minimize'fire hazard.

As shown in Figs. '3 and 4, the wall portion 30 (of heat insulatingmaterial) may be const'ructed to form a ridge 3|, while the plate 32 maybe constructed to 'form an incline 33 towards a drain hole 34, whichdrain hole 34 will lead to .the conventional drain pip 35. Pipe nipples36 are embedded in plate or pan member P which includes plate 32, andthose not bein used are covered by means of conventional pipe caps 3''.Otherwise, conventional couplings 38 *are' used to .connect the nipples36 to pipes 39.

At 40, 40', the sprinkler heads are shown as being attached by means ofnipples 4'l, 4l'-to water pipe 42, by means of a passage 43 provided inplate 32 soas to connect the pipe 42 with nip- In instances where thepipes are located such as .to permit same to be closed in, conventionaldoors 45 may be used, hingedly secured to a door frame 46. Opening 4!will permit communication with space 48 in which the various pipes areconcealed.

As illustrated in Figs. 3 to 8 inclusive, a flange 50 is provided in theplate member P or 55 to facilitate thesecurement of said member to the"-fioor arch l9 of'the rooms through which the piping passes. It isunderstood that the visible bottom surface of such flange 50 may becovered "with decorative design (not shown) as desired.

' In Figs. 3 and 4, a plurality of pipe connections are shown; whereas,in Figs. and 6, there is depicted the plate member P having an integralpipe fitting passing through its plate 52 and connected to a single pipe5!, said plate P closing an opening 53 in floor 54 through which thepipe 5 f'pas'ses.

In Figs. '7 and 8, another typical plate arrangement is illustrated, theplate member 55 comprising insulating member 59 provided with side walls56 and enclosing plate 60 having an inclined floor 51 draining towards-adrain hole 58. Embedded in the plate 60 and the insulating member 59 arevarious types of conventional pipe connections 6 lvariations of pipefittings may be included.

f Instead of using actual pipe fittings, it is understood thatequivalent ducts or passages may be cast or formed in the plate or panduring process of 'manufacture, which ducts may have their inlet and/oroutlet either fiush'with the surface of the pan or projectedtherebeyond. ;Therefore,

shown in Fig. 8 may where the term pipe fitting is used in the claims,it is to be understood that this term also embraces or means suchpassages or the equivalent thereof.

Ininstances where it is desired to dispose the plate member aroundexisting pipes, the said plate member may be constructed ininterengaging or interlocking sections, as illustrated in Figs, 9 and10, one or more sections being provided with integral pipe nipples orfittings as aforementioned. The typical arrangement shown in Fig. 9,

- provides for four plate sections 15, 76, H and 18,

inclusive. These plate sections may be secured to the floor arch 19 bymeans of screws 88. Passages 8| are cut out of the bevelled edges 82 ofsuch sections to facilitate the passage of pipes or pipe nipples 83. Toinsure a tight fit of such sections of plates, the same may be bevelledas clearly illustrated at 85.

Auxiliary locking means may be provided for these sectional plates 15-18inclusive, in the form of bevelled tongue members 86 registering withnotches 81, as clearly illustrated in Fig. 9.

From the foregoing it will be readily seen that means of simpleconstruction have .been provided to overcome any and alldiflicultiesencountered by plumbers, steam fitters, etc., when installin pipings .inbuildings as regards openings left around pipes in ceilings and floorsof a building, which in many cases are not only unsightly but alsoadanger to the health and safety of occupants or tenants. Ashereinbefore mentioned such cracks promote infestation of vermin as wellas offering a passage for odors, smoke, condensation from one floor toanother.

While typical plate and pipe nipple arrangementsare shown, it is, ofcourse, understood that many other combinations and arrangements arepossible to be, manufactured as to, meet varied local conditions. I

With regard to the plates shown in Figs. 9 and 10, many variations arepossible, such as, for example, the omission of the locking tongue andnotch portions. The edge of the opening 8| may be closed by soldering,;cementing,'etc., after the cover plate has been installed.

Thus, there has been provided herein a pan or plate-like member (P ofFig. 1, P, 32 of Figs. 3, 4; 55 of Fig. 8) in a structure having anopening, said member having a passage comprising a pipe fitting (21 ofFigs. 1, 2; 3'6, 43 of Fig. 3; iii, 62, 63 of Fig. 8) forming anintegral part of said member, said member being secured to saidstructure adjacent said opening sealing said opening around saidpipe-fitting, the pipe-fitting being adapted Although tnerore oifig isdescriptive of the best known embodiments of the invention, it will beunderstood as descriptive-rather than restrictive, and subject to suchchanges and modifications as may come within the scope of the appendedclaims.
